This efficiency was chosen as an industrial practice “average” from the data presented in Fig. 6.(PDF) Closed circuit ball mill – Basics revisited | Walter,,The reference point is a conventional ball mill circuit in closed circuit with cyclones operating at 250% circulating load and having 38% of fine material reporting to cyclone underflow, resulting in a classification efficiency of 50%.VALIDATION OF A CLOSED CIRCUIT BALL MILL MODEL Alex,,given mill is doubled by including a closed circuit classifier producing a 200% circulating load. Similarly, by increasing the circulating load to 500% the capacity factor increases to 2.3. Figure 1. Effect of circulating load on mill capacity [5] Research into the subject of classification efficiency effect on grinding circuitHigh recirculating loads in Ball Mill Circuits - Grinding,,High circulating load is common in both reverse and direct ball mill grinding circuits. Why? Because the ball mill closed circuit is the last stage before separation. Cyclone overflow should be clean of coarse particles. About the big pump, it’s one of the most important equipment when you are going to
